Abstract Large bloom and round section casters with soft reduction technique must face the opposite choice of roller face shape which is whether arc shaped face is used or not. For the round section, using arc shaped roller face is necessary to ensure strand alignment. But for the bloom section, when soft reduction is applyied, with very large pressure, arc shaped roller face can form hump on bloom surface, which is obviously unacceptable. So the bloom section and the round section have the different requirement for roller face shape of withdrawing and straightening unit. How to solve this problem is the key point for the using of soft reduction in bloom and round section casters. According to author’s experience in real engineering practice, a new idea have been put forward to solve this problem.
